After ovulation, the wall of the ruptured follicular cavity folds in.
Slight haemorrhage occurs at the site of ovulation and fills the former cavity.
This is known as the Corpus Haemorrhagicum.
As the blood is resorbed, a solid Corpus Luteum is formed by proliferation of granulosa and theca intera cells as well as blood vessels.
In the non-pregnant animal, corpora lutea are transient structures.
Cyclic corpora lutea undergo proliferation and vascularisation directly after ovulation.
The corpora lutea then regress and degenerate into a connective tissue scar, the Corpus Albicans.
If the ovum is fertilised, the corpus luteum remains fully developed and active throughout at least part of the pregnancy.
Corpora lutea produce progesterone.
Progesterone prepares and maintains the uterus for implantation of the fertilised ovum.
